Celebrity Parents It's a Boy for Ashlee & Pete! They name him Bronx Mowgli Wentz and "thank everyone for their well-wishes!" a rep tells PEOPLE By Marisa Laudadio Published on November 21, 2008 02:00 AM Share Tweet Pin Email Ashlee Simpson-Wentz and husband Pete Wentz welcomed a son Thursday night, PEOPLE confirms. Bronx Mowgli Wentz weighed 7 lbs., 11 oz., and was 20 1/2 inches long. “Ashlee, Pete and baby Bronx are all healthy and happy, and thank everyone for their well wishes!” a spokesperson tells PEOPLE. Simpson-Wentz, 24, and the Fall Out Boy bassist, 29, announced her pregnancy in May, a few weeks after their opulent Alice’s Adventures In Wonderland-themed wedding. “I would love to have a big family one day,” Simpson-Wentz told PEOPLE at the time. Added Wentz: “A big soccer team or a band!” And, as her dad, Joe Simpson, recently put it to PEOPLE: “The day she found out she was pregnant, she became a woman.” Wentz, meanwhile, has been leaning on rocker pal Joel Madden – dad to 9-month-old Harlow with girlfriend Nicole Richie – for tips on fatherhood. “Joel gives me advice,” Wentz recently told PEOPLE. “[It’s] been really awesome for me to go to another person my age.” Richie and Harlow were guests at Simpson-Wentz’s Winnie the Pooh-themed baby shower on Nov. 1. Wentz also has another kind of baby on the way: Fall Out Boy’s third album, Folie A Deux, will be released on Dec. 16. • Click here to congratulate Pete and Ashlee on baby Bronx RELATED GALLERIES:• Ashlee & Pete wed in Alice in Wonderland-themed ceremony• Read more about Hollywood’s baby boom!
